** The configure option `--with-pkg-config-prog' has been removed.
Use './configure PKG_CONFIG=/full/name/of/pkg-config' if you need to.
-** The configure option '--enable-silent-rules' and the command
-'make V=0' now do a better job of suppressing chatter.
+** The configure option '--enable-silent-rules' is now the default,
+and silent rules are now quieter. To get the old behavior where
+'make' chatters a lot, configure with '--disable-silent-rules' or
+build with 'make V=1'.

** The `grep-changelog' script (and its manual page) are no longer included.
\f
* Changes in Emacs 25.1
+** `package-install-from-buffer' and `package-install-file' work on directories.
+This follows the same rules as installing from a .tar file, except the
+-pkg file is optional.
+
** New function `custom-prompt-customize-unsaved-options' checks for
unsaved customizations and prompts user to customize (if found).
** A new text property `inhibit-read-only' can be used in read-only
buffers to allow certain parts of the text to be writable.
-** A new function `file-tree-walk' allows to apply a certain action
-to all the files and subdirectories of a directory, similarly to the C
-library function `ftw'.
-
** A new function `directory-files-recursively' returns all matching
files (recursively) under a directory.

* Editing Changes in Emacs 25.1
+** Unicode names entered via C-x 8 RET now use substring completion by default.
+
** New minor mode global-eldoc-mode is enabled by default.
** Emacs now supports "bracketed paste mode" when running on a terminal
When you invoke `shell' interactively, the *shell* buffer will now
display in a new window. However, you can customize this behavior via
-the new `shell-display-buffer-actions' variable. For example, to get
+the `display-buffer-alist' variable. For example, to get
the old behavior -- *shell* buffer displays in current window -- use
-(setq shell-display-buffer-actions '(display-buffer-same-window)).
+(add-to-list 'display-buffer-alist
+ '("^\\*shell\\*$" . (display-buffer-same-window))).
+
+** EIEIO
+*** The `:protection' slot option is not obeyed any more.
+*** The `newname' argument to constructors is optional&deprecated.
+If you need your objects to be named, do it by inheriting from `eieio-named'.
+*** The <class>-list-p and <class>-child-p functions are declared obsolete.
+*** The <class> variables are declared obsolete.
+*** The <initarg> variables are declared obsolete.
** ido
*** New command `ido-bury-buffer-at-head' bound to C-S-b
Bury the buffer at the head of `ido-matches', analogous to how C-k

** `Info-fontify-maximum-menu-size' can be t for no limit.
++++
+** `info-display-manual' can now be given a prefix argument which (any
+non-nil value) directs the command to limit the completion
+alternatives to currently visited manuals.
+

** ntlm.el has support for NTLM2.
\f
* New Modes and Packages in Emacs 25.1
+** cl-generic.el provides CLOS-style multiple-dispatch generic functions.
+
** scss-mode (a minor variant of css-mode)
** let-alist is a new macro (and a package) that allows one to easily
let-bind the values stored in an alist.
+** `tildify-mode' allows to automatically insert hard spaces as one
+types the text. Breaking line after a single-character words is
+forbidden by Czech and Polish typography (and may be discouraged in
+other languages), so `auto-tildify-mode' makes it easier to create
+a typographically-correct documents.
\f
* Incompatible Lisp Changes in Emacs 25.1
** Function `sort' can deal with vectors.
+** Function `system-name' now returns an updated value if the current
+system's name has changed or if the Emacs process has changed systems,
+and to avoid long waits it no longer consults DNS to canonicalize the
+name. The variable `system-name' is now obsolete.
+
++++
+** Function `write-region' no longer outputs "Wrote FILE" in batch mode.
+
---
** New utilities in subr-x.el:
*** New macros `if-let' and `when-let' allow defining bindings and to
undocumented integer-pair format. Instead, they return a list of two
integers.
++++
+** New function `set-binary-mode' allows to switch a standard stream
+of the Emacs process to binary I/O mode.
+
\f
* Changes in Frames and Windows Code in Emacs 25.1
`scroll-bar-height'.

+** The height of a frame's menu and tool bar are no longer counted in the
frame's text height. This means that the text height stands only for
the height of the frame's root window plus that of the echo area (if
present). This was already the behavior for frames with external tool
